What is the factored form of x^3 -1
lianna [129]

Answer:

The factored form of x^3 -1 will be:

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

Step-by-step explanation:

Given the expression

x^3-1

Rewrite 1 as 1³

=x^3-1^3

\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

            =\left(x-1\right)\left(x^2+x+1\right)

Thus, the factored form of x^3 -1 will be:

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is
harkovskaia [24]

Answer: h=5.66ft

Step-by-step explanation:

Observe the picture attached.

Find the value of "x" and "y" using the Pythagoren Theorem:

a^2=b^2+c^2

If you solve for "a":

a= \sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case, for "x" you know that:

a=x\\b=8ft\\c=2ft

Then, the value of "x" is:

x=\sqrt{(8ft)^2+(2ft)^2}\\\\x=8.24ft

For "y" you can see that:

a=10ft\\b=8.24ft\\c=h

Subsituting values and solving for h, you get:

(10ft)^2=(8.24ft)^2+h^2\\\\h=\sqrt{(10ft)^2-(8.24ft)^2} \\\\h=5.66ft
